Mashed potatoes are a popular side dish that can be enjoyed as part of many meals. They are often made in large batches and can be stored for later use. But how long can you keep cooked mashed potatoes before they go bad?

The shelf life of cooked mashed potatoes depends on how they are stored and the conditions in which they are kept. If stored properly, cooked mashed potatoes can last for up to five days in the refrigerator.

It is important to store cooked mashed potatoes in an airtight container to prevent them from drying out and absorbing odors from other foods in the refrigerator. Additionally, it is recommended to keep them in the back of the refrigerator, where the temperature is usually the coldest.

When reheating leftover mashed potatoes, it is best to do so on the stove or in the oven, as microwaving can result in a less desirable texture. Adding a little bit of milk or butter while reheating can help restore the creamy consistency.

Remember to always use your senses to determine if cooked mashed potatoes are still good to eat. If they have a strange smell, texture, or taste, it is best to discard them to avoid any potential foodborne illnesses.
